[Samsung Galaxy Nexus] Cuissedemouche:
Thanks for your answer, I tried to flash repit my GN, first, it failed because I launch it form /SDCARD, so I move it to /tmp and execute it again, I also had an error because of /data partition.

Here the log:

e2fsck: Bad magic number in super-block while trying to open /dev/block/mmcblk0p12

/dev/block/mmcblk0p12:

The superblock could not be read or does not describe a correct ext2

filesystem. If the device is valid and it really contains an ext2

filesystem (and not swap or ufs or something else), then the superblock

is corrupt, and you might try running e2fsck with an alternate superblock:

e2fsck -b 8193 <device>

FATAL: file system errors in partition #12 'data' (userdata) could not be automatically fixed (try running 'e2fsck -f /dev/block/mmcblk0p12')

[ERROR 1]

EDIT : It seems that the script configure the /data in ext4 :

data = size:same + content:keep + fs:ext4

Can it be that ?

EDIT 2 : I change the name of the file to lanchon-repit-20160415-system=1.0-cache=0.0605+wipe-data=same+keep+f2fs-maguro.zip and it seems to be good. So I ask help for nothing sorry^^
